Table 6 Summary of fatigue failure tests: maximal load, vertical & lateral stiffness, number of cycles (all values prior to failure) and failure types. The values of the first 5 groups have been retrieved from our previous studies and reported here for comparison purposes. All the differences were not statistically significant
